METHOD OF PREPARING SUBSTITUTED 2-(PHENYLAMINO)-2- IMIDAZOLINES
FIELD: chemical industry. SUBSTANCE: substituted 2-(phenylamino)-2-imidazolines of formula I: wherein R1= R2= Cl and R3= H, CH3, F, are prepared by condensation of anilines with 1-benzoylimidazolidin-2-one in phosphorus oxychloride in the presence of lithium halides or quaternary ammonium bases.
